" roeand State .of New York, have invented "certain new and useful improvements in Primers, of which. the following is a specigfication.

' The object of this inventicin to provide a priming device in connection with carburetor.

In the drawings, Figure l is a side elevation of the carburetor, the lie-at feed chamher being shown pa tly i section, the section being taken on the line l*1* of Fig. 2. Fig. 2 is a horizontal section through the float feed chamber, the section being taken on the line 2*-2" of Fig. 1.

In the drawings like reference numerals indicate like reference characters.

. 1n the drawings, reference numeral 1 indicates a float feed chamber in which is carried a supply of gasolene; 2 an intake through which the gasolene is fed into the carbureter. a V

'3 indicates a compartment in which the needle valve of the carbureter is carried and 1 indicates the casing for the mixing chamber of thecarbureter. At the top of the mixing chamber is pivotally mounted a throttle valve 5 operated by a crank {l to which is'connected a link having a section 7 which telescopes in the section 8 and be in clamped thereto by a split sleeve at 9.

film 'fiOZlt chamber of the carlnlrctm: is provided with a lateral extension 1.0 which is shaped to contain gasolcnc and a valve without interfering with the operation oi the float that is contained in the float chamber. Formed in the extension 10 is a valve seat 11 in which is pivotally mounted a valve 12 which valve is surrounded by a stulfing box 13. The valve 12 has a longi tudinal opening 14 t. erein closed by a screw 15. The valve 12 also is provided with the lateral openings 16 and 17 both of which communicate with the longitudinal opening H. Connected with the lateral opening 16 is a tube 18. In line with the lateral open ing 17 is an opening 19 in the valve seat 11. Surroundin this opening 19 is a boss 20 into which is threaded a tube 2-1 which ex tends upwardly and communicates with the interior of the mixing chamber of the car-- bureter above the throttle valve.

The parts are so arranged that when the specification of Letters Patent.

valve is in the position shown in full lines in Fig. 1, gasolcnc 'an pass up through the tube 15'! into the longitudinal opening oi the valve 12 and along this opening through the opening 1? and up through the tube 21. into the mixing chamber of the carburetor above the throttle valve. When the valve 12 is given a quarter turn, the tube It; will assume the dotted line position shown in Fig. 1 and the ope 1g 1. of the valve 12 will be closed be tube 21.

pcration of my priming device is l ows the engine 01"." the automobile is about to be started, the throttle valve 5 is moved to close the opening at the top of the mixing chamber and the valve. 12 is set with the tube 18 in the position shown in 1. The engine is then turned over once and this wil cause the gasolcnc to be sucked up from the float chamber through the tube 18. 'alvc 12 and tube 21 from which it will be discharged on the throttle valve 5. The valve 12 is then closed. The throttle valve is then opened and as the engine is further rotated, the air will be drawn past the throttle valve 5, which then acts as a ballie from which the gasolone held thereon may be cvaporatml by the air, enriching the mixture as it passes into the engine. In this manner, a rich mixture is fed into the err ginc. A stationary baillc may be used to hold the gasolcno dischargml from the tube 21 in which case the alvc 5 would act as a throttle only to produce the suction. The tube 21 may extend down into the gasolenc. pcrinl'incntly and the valve may be arranged to permit and still regulate the flow through the tube and such a modification is within the scope of my invention.

I claim:

1. In a carburetor the combination of a lioat chamber and a mixing chamber, a throttle valve in themixing chamber, a tube extending from the top of the float chainber into the mixing chamber above the throttle valve, a valve at the top of the float chamber opening and closing said tube, said valve having a tubular extension thereon that dips into the gasolcnc when the valve is open and is raised from the gasolcne when the valve is closed.

9,. in a carburetor the combination oi afloat chamb r, a tube extendiup up from said chamber, a valve in said chamber normally closing said tube, a tube on said valve normally held above the gasolene in the chamber when the valve closes the tube, the

end of said tube being immersed in the gasolene when the valve opens said tube.

3. In a'carbureter the'combination of a float chamber, a tube extending up from said chamber, a valve in said chamber normally closin said tube, a tube on said valve normally he ld above the gasolene in the chamber when the valve closes the tube, the

end of said tube being immersed in the gasolene' when the valve opens said tube, a llll.\'- ing chamber, a throttle valve therein, said tube opening into said mixing chamber above the throttle 'alve.

4. In a carbnreter the combination of a float chamber, a tube extending up from said chamber, a valve in said chamber normally closing said tube, a tube on said valve normally held above the gasolene in the qhamber when the valve closes the tube, the

end of said tube being immersed in the gasolene when the valve opens said tube, a
